CHARLES M. BYRD AND GEORGE H. TRAVIS, OF BATTLECREEK, MICHIGAN.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 779,026, dated January3, 1905.

Application filed April Z3, 1904. Serial No. 204,657.

To all whom t Netty concern:

Be it lr'nown that we, CHARLES M. BYRD and GEORGE H. TRAVIS, citizens ofthe United States, residing at Battlecreek, in the county of Calhoun andState of Michigan, have invented certain new and useful Improvements inLubricators, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates more especially to that class of lubricatorsdesigned for use upon locomotives and for this purpose is arranged tofeed both sides of the engine and the air-pump separately andindependently.

The object of this invention is to provide means for positivelydelivering the required amount of oil to each of the several steamchestswithout danger of cross feeding or burning the lubricating elements, asWill hereinafter appear.

In the arrangement of parts our lubricator consists of a cylindricaloil-reservoir upon which is mounted the condensing-chamber, which isdivided into several compartments by vertical walls reaching nearly tothe bottom of the chamber, where they are united by a common passageunderneath the walls. Displacement-water from the condensing-chamber isconducted to the bottom of the oil-reservoir by means of a pendent tubeand connecting valved passages. The steam connection to thecondensing-chamber is below the oil-outlet lines, thereby promotingcondensation and preventing the oil from being exposed to the directiniiuence of live dry steam, which would damage or destroy thelubricating elements in the oil, especially if used on very highpressure, as is now common. As the compartments in thecondensing-chamber are absolutely without intercommunication in the lineof oil-passages, it is obvious that crossfeeding is impossible. Thepeculiar manner of making the steam connection not only prevents undueand dangerous heating of the oil, but forms a Water-trap whicheiiectually prevents oil entering the boiler from the lubricator underany circumstances. The condenser and oil-reservoir being an integralcasting, all unnecessary joints are avoided. The close proximity ofthese chambers also insures the oil in the reserv'oiralways being warmenough to flow readily regardless of the temperature of the airsurrounding the cup.

In the accompanying drawings, Figure l is a front central verticalsection. Fig. 2 is a vertical cross-section, and Fig. 3 is a horizontalsection through dotted lines in Figs. l and 2.

Similar parts are indicated by like letters in each of the views.

A is the oil-reservoir.

a is the condensation lead-pipe.

Bis the condensing-chamber,with compartments b S is the steam-pipeconnection to boiler.

e e e are the openings from steam-line into condensing-chambercompartments.

g g g are the sight-glasses.

G G are the glass caps.

V V V are the feed-regulating valves.

W is the regulating-valve for displacement- 'water.

K K K are the inlets to regulating-valves.

t 7," t are the oil-drop nipples.

/t la la /L are the valve-stem boxes.

71 7l z' r1 are the box-gland nuts.

s s s are cap-plugs.

p is a pipe-plug for one end of steam-inlet passage.'

D is a bracket-stud to support the lubricator in position.

F is the filling-plug.

f is the filling-opening.

C C C are the choke-tubes.

E E E are the delivery-nipples.

U U U" are the pipe-unions.

T T T are the tallow-pipes.

m a are holes connecting displacement valve and tube with condenser andthe oil-chamber.

The operation is as follows: Steam from the boiler having been admittedto pipe S and the condensing-chamber filled with -water up to line ofoil-outlets, the regulating-valve to( displacement-water is opened andthe feedvalves V V V adjusted to meet expected requirements, water willpass down tube c as fast as room is made for it by escape of oil upwardthrough nipples t t/ t to the several compartments and tallow-pipesleading therei from'. As the steam-inlet to the condensingchamber fromboiler is submerged, it is obvious that the oil and steam cannot comeinto a direct contact and only oil and water can pass from the chamberto the tallow-pipes, thereby not only preventing the burning of the oiland consequent damage to same, but leaving no burned residue to clog andobstruct the talloW-pipes. Y

Having thus fully illustrated and described our invention, what we claimas new, and desire to secure by Letters Patent of the United States, is-

l. A lubricator consisting of a casting having an oil-reservoir and acondensing-chamber therein, said condensing-chamber having partitionsforming compartments each closed at the top to prevent cross-feeding ofoil therein, communication being established between each of saidcompartments and the oil-reservoir and means for regulating saidcommunications, and the wall of each of said compartments having anoil-outlet and a steam-inlet.

2. The combination in a lubricator of an oil-reservoir and acondensing-chamber separated by a partition, said condensing-chamberhaving iianges depending from the top thereof forming compartmentstherein, nipples in the condensing chamber providing communication Withthe oil-reservoir and a valve for regulating each of suchcommunications, there being an oil-outlet and steam-inlet in the wall ofeach of said compartments, and a condensation-pipe leading from thecondensing-chamber to the oil-reservoir.

3. In a lubricator, a casing having a partition therein forming anoil-reservoir and a condensing-chamber, said condensing-chamber havingiianges depending from the top thereof forming compartments therein, anoilnipple and regulating-valve located between each of said compartmentsand the oil-reservoir, and said casing having the steam-inlet locatedbelow the oil-outlet therein to each of said compartments.

4. The combination in a lubricator, of a casing having an oil-chamberand a condensingchamber, nipples and valves for regulating communicationbetween said chambers, observation-glasses in said condensing-chamberopposite said nipples, said casing having an oil -outlet near the top of-the condensingchamber and there being a steam-inlet in the casingconnected to saidcondensing-chamber below the water-line therein.

In testimony whereof1 We affix our signatures in presence of twowitnesses.
